Configuration of a circular rigid-walled pipeline in the cylindrical coordinate system with r , θ , and z being the radial, circumferential, and axial directions respectively. The pipeline radius and wall temperature are denoted by R and T wall, respectively, with ν 0 ( r ) being the shear flow profile.
